Easy&Cheap(no Soidering) Annoyance Beeper!

Introduction: Easy&Cheap(no Soidering) Annoyance Beeper!

There was a sudden beep in my garage I had never heard it before so I started looking but couldn’t find the source .I didn't hear it again the whole time I searched for it but when I went to leave....BEEP! It took me 6 months to find that annoying little beep I searched high and low but for naught! Finally one day I happened to have it in my hand when it beeped and when it did I screamed like a little girl.... I was that surprised (and pleased )to find it. Turns out that beep was coming from an old smoke alarm we had out there because we had bought new ones. They start beeping intermittently when their battery is running low. I found out about this the hard way, but my embarrassing situation Is your gain because the idea hit me if it took me that long to find something so obvious...It would take somebody I deemed worthy of an annoyance ,at least twice that long if made it smaller and easier to Hide. MMAAAUHHHHHHHHHHHhhhh...sorry I lost it there for a sec...Now back to our evil plan!

What you will need:
1. An old smoke alarm
2. A small flat head screwdriver (I use a steak knife but in retrospect ....)
3. An Dying 9 volt battery (stick it your tongue for an hour.)...it work for my brother Dewey; P (but ... of course he's Dewey)
4. The victim...er...subject.
5. A genuine disdain for the sanity of mankind....or woman kind.

Step 5: 5

Step 6: 6

Now hide it ( you can do a better job hiding than I did)
Sit back and watch the fun. :D the better you hide the harder it is for them to find and since the beep doesn't happen on a regular intervals it makes it that much harder to find Have fun!

I've actually debated about taking the radioactive smoke detectors out of my house, and getting the photo detecting ones.

You all should look up the Nuclear boy scout, it's about a man by the name of david hahn. When he was 13 he made a nuclear reactor in his back yard and having the nuc hasmat team dismantal his mothers garden shed. Majority of his nuclear materials came from Smoke detectors.

i would kind of worry about taking the smoke alarm apart as there is a small amount of a radioactive substance in there called americium-241. its small but can be harmfull if taken from its container. but besides that great project :-] (t-up)

Not enough to do much to you really, took one apart before and under the metal cap, its just a sealed metal container with the stuff inside it. I'm only 13 and nothing has happened to me and it sits chucked about in my bedroom every day...

Nothing to worry about. The alpha particles emitted by the Americium - 241 can't even penetrate the layer of dead skin cells covering your body! The only problem is from if you eat it or inhale it. Even if you do, the amount in a smoke detector is only about 1 micro-curie. Basically harmless.

It is something that you should keep in mind but because of the low penetration of alpha radiation in Americium-241 is only a health risk when ingested or inhaled, so if you are only taking the components from the smoke alarm out of the case and you are not actually taking apart the components it should be ok.

much quicker too. who wants to burn a nine volt into your tongue for an hour or two? not me.

a similar, but much easier to find (and much harder to stop) prank would be to take one of those magnetic window alarms they sell at like dollar general, remove the magnetic piece, and chuck it into a room (preferably at night, when the victim is asleep >:)

some models dont have an off switch as far as i know. they wont turn off untill the magnet is returned, or the battery runs down.
